Kohaku began to enlarge at a wild rate. Inuyasha and Kohaku had been grappling so when Kohaku started to grow, Inuyasha was raised off the ground. Kohaku's feet plowed through the forest and overtook the gang on the ground who were soon trapped between his big and second toe. Kohaku continued to grow until he reached a height of 5000 feet. Inuyasha was smaller than his toes and therefore couldn't defeat him.
